Sei Network is a high-performance Layer 1 blockchain engineered specifically for trading applications across the decentralized ecosystem. Co-founded by Jayendra Jog and Jeff Feng, Sei launched in 2023 as an open-source platform designed to deliver unmatched speed, scalability, and efficiency. Its native cryptocurrency, Sei coin (SEI), powers transactions, staking, governance, and smart contract operations on the network.
Built with decentralized exchanges (DEXs), NFT marketplaces, and blockchain gaming in mind, Sei stands out due to its record-breaking transaction finality and throughput. Thanks to its proprietary Twin Turbo Consensus mechanism, Sei can process up to 5,030 transactions per second (TPS), with a theoretical peak of 12,500 TPS—finalizing blocks in just 300 milliseconds. This makes it one of the fastest blockchains globally, perfectly suited for high-frequency trading and real-time applications.
How Does Sei Network Work?
At the core of Sei Network’s performance lies a suite of innovative technologies that redefine blockchain efficiency.
Twin Turbo Consensus
The foundation of Sei’s speed is its Twin Turbo Consensus, a dual-engine system combining two groundbreaking techniques:
- Intelligent Block Propagation: This feature predicts which validator will propose the next block and pre-sends transaction data ahead of time. By reducing communication overhead during block creation, it significantly cuts down latency.
- Optimistic Block Processing: Instead of waiting for full validation, Sei assumes transactions are valid by default and processes them immediately. If any inconsistency is detected later, corrections are made—this "assume success first" approach accelerates throughput without compromising security.
Together, these mechanisms enable near-instant transaction finalization and position Sei as a leader in low-latency blockchain infrastructure.
Parallel Order Execution
Traditional blockchains handle transactions sequentially—even if they involve unrelated assets. Sei changes this with Parallel Order Execution, allowing multiple orders from different markets to be processed simultaneously. For example, a trade on a Solana-based token pair and an Ethereum-based pair can be executed in parallel rather than queued.
This capability dramatically increases efficiency for DEXs and trading platforms, where thousands of orders may flood the network at once.
Native Order-Matching Engine
Sei integrates a built-in order-matching engine directly into the blockchain layer. Unlike most networks that rely on off-chain or smart contract-based matching systems, Sei handles buy/sell order pairing natively—making trades faster, cheaper, and more reliable.
Combined with Market-Based Parallelization, which identifies independent markets and processes their transactions concurrently, Sei delivers a seamless experience for developers building high-speed trading applications.

The Role of Sei Coin in the Ecosystem
Sei coin (SEI) is the lifeblood of the Sei Network, enabling all on-chain activities. More than just a tradable asset, SEI plays several critical roles:
1. Transaction Fees
Every action on the network—whether sending tokens, interacting with dApps, or executing smart contracts—requires gas fees paid in SEI. These fees incentivize validators to secure the network and maintain consensus.
2. Staking & Rewards
Holders can stake SEI to become validators or delegate their stake to existing ones. In return, they earn staking rewards in additional SEI tokens—a passive income model that also strengthens network decentralization and security.
3. Native Collateral
Applications built on Sei can use SEI as native collateral for lending protocols, derivatives platforms, or synthetic asset issuance. This deep integration enhances liquidity and usability across DeFi dApps.
4. Fee Markets
Users who need urgent transaction processing can offer tips (priority fees) in SEI to validators. This creates a dynamic fee market where speed-sensitive traders can jump the queue during peak congestion.
5. Governance Participation
As Sei evolves toward full decentralization, SEI holders will vote on protocol upgrades, treasury allocations, and ecosystem development proposals. This ensures community-driven decision-making aligned with long-term growth.
With utility spanning performance, economics, and governance, Sei coin is central to the network’s sustainability and user engagement.
How to Bridge Assets to Sei Network
To interact with dApps, trade on DEXs, or stake on Sei, you’ll need to transfer assets from other chains like Ethereum or Binance Smart Chain. Cross-chain bridging allows seamless movement of tokens while preserving Sei’s speed and low cost.
Here’s a step-by-step guide:
Step 1: Connect Your Wallet
Use a compatible wallet such as MetaMask or Compass. Ensure it’s connected to the source network (e.g., Ethereum) where your funds currently reside.
👉 Start bridging assets securely and efficiently today.
Step 2: Select Source and Destination Chains
Choose your current network (e.g., Ethereum) as the source and Sei Network as the destination. Confirm the supported token you wish to bridge (e.g., USDT, ETH, WBTC).
Step 3: Enter Transfer Amount
Input the amount you want to move. Make sure you leave enough balance to cover gas fees on both chains.
Step 4: Provide Your Sei Wallet Address
Paste your receiving address from a supported Sei wallet (e.g., Compass or Fin Wallet). Double-check for accuracy—transactions cannot be reversed.
Step 5: Confirm and Execute
Review all details carefully: amount, networks, fees, and address. Then confirm the transaction through your wallet interface.
Step 6: Wait for Completion
Most bridges finalize within minutes. Once done, your assets will appear in your Sei wallet, ready for use in DeFi, NFTs, or gaming apps.
Pro Tip: Many cross-chain platforms support bridging from Solana, BSC, Tron, TON, Aptos, Sui, and others—giving you full flexibility to bring assets from major ecosystems into Sei’s high-speed environment.
